Daddy and Sally sold their motor home after last summer's vacation so this year we decided to rent a place at Glacier National Park. We found a nice house in West Glacier looking out on a golf course. It was fun sitting on the deck with a glass of wine watching all the duffers.
The day was beautiful and I changed into my bikini. I grabbed a bottle of wine and two glasses and invited Sally to join me on the back deck to watch the golf while Daddy and Jim went trout fishing.
My black bikini contrasted well with my pale skin from the long winter and I knew I looked good wearing it. But it was Sally's red bikini that stole the show. It was transparent plastic. From a distance it looked just like a red bikini. But up close you could see Sally's nipples and her dark pubic hair through the translucent plastic.
The red plastic didn't breathe and it wasn't long before Sally's pussy was wet and juicy and her sweaty nipples were smashed up against the red plastic of the bra.
"Isn't the plastic hot?" I asked her.
"Yes," she replied. "Your father likes the sweat when we make love. I make him wear his plastic panties until his balls are dripping in sweat. His sweaty cock slides smoothly in and out of my pussy."
My fingers were down the top of my bikini fiddling with my clit. "You wouldn't happen to have a pair of plastic panties I could borrow, do you?"
That's how Daddy and Jim found Sally and me sitting on the back deck, half snockered, wearing transparent plastic underwear.
Sally told Daddy to go change. "And let Jim borrow a pair of your plastic panties."
We were all sitting on the deck wearing our plastic panties when I asked, "Have you tried latex instead of plastic?"
"Yes, but there's nothing like the feel of plastic rubbing on my dick," Daddy said. "I'm horny all the time.
